My 23hp Vanguard motor stalls every so often, To restart it I have to turn the battery isolator switch off then back on again before it will restart. could it be to do with the oil pressure switch

Stalling
yes oil pressure switch's /modules are wired in to the spark systems of small plant motors as motor protection

i cant see one listed as a part for sale for 23 hp vanguard briggs
or mentioned in the user manual
386447 3079

if oil level is ok and oil pressure switch isnt the problem

check the governor adjustment
or adjust the idle




very simplistic drawing
